PEANUT BUTTER WHISTLE, IS WHEN YOUR FINGERING A FEMALE WITH 2 FINGERS AND YOU MAKE HER LICK IT ALL OFF! ( YOU USE TWO FINGERS TO WHISTLE SO IT LOOKS LIKE SHES GETTING READY TO WHISTLE WITH THOSE FINGERS).

I STUCK MY 2 FINGERS SO DEEP IN KHIAS ASS THAT MADE HER ALL HOT AND HORNY. SO SHE GRABBED MY FINGERS AND GAVE HER SELF A PEANUT BUTTER WHISTLE!
